Connect frame,
Left socle includes left front support 11, the lower-left push rod 12 being slidably connected on left front support 11,
The bottom right push rod 22 that right support includes right anterior branch frame 21, is slidably connected on right anterior branch frame 21,
Frame locking mechanism includes the lower-left locking mechanism being arranged between left front support 11 and lower-left push rod 12, be arranged at the right side before
Bottom right locking mechanism between support 21 and bottom right push rod 22,
Left socle also includes that the upper left changed between lock-out state and released state by rotating realization control lower-left locking mechanism pushes away
Bar 13, the bottom of upper left push rod 13 is rotatably connected on the upper end of lower-left push rod 12, frame locking mechanism around the first from left axle 31
Including the upper left locking mechanism being arranged between lower-left push rod 12 and upper left push rod 13；
Right support also includes that the upper right changed between lock-out state and released state by rotating realization control bottom right locking mechanism pushes away
Bar 23, the bottom of upper right push rod 23 is rotatably connected on the upper end of bottom right push rod 22, frame locking mechanism around a right axle 41
Including the upper right locking mechanism being arranged between bottom right push rod 22 and upper right push rod 23.
Upper left locking mechanism and the concrete structure of upper right locking mechanism, be not the main points of the present invention, as long as can turn two
Between dynamic parts, the structure of locking can be suitable at this, does not repeats them here.
Upper left push rod 13 includes upper left putter body 131, is fixed on a left side for a sidepiece of the bottom of upper left putter body 131
Lower end rotating disk, lower-left push rod 12 includes lower-left putter body 121, is fixed on a sidepiece of the upper end of lower-left putter body 121
Left upper end rotating disk, lower-left end rotating disk and left upper end rotating disk be rotationally connected by the first from left axle 31, and lower-left locking mechanism includes rotating
Or the left touch switch portion 122 being slidably arranged in lower-left putter body 121, upper right push rod 23 includes upper right putter body
231, being fixed on the bottom righthand side rotating disk of a sidepiece of the bottom of upper right putter body 231, bottom right push rod 22 includes bottom right push rod
Body 221, it is fixed on the upper right side rotating disk of a sidepiece of the upper end of bottom right putter body 221, bottom righthand side rotating disk and upper right side
Rotating disk is rotationally connected by a right axle 41, and bottom right locking mechanism includes rotating or being slidably arranged in bottom right putter body 221
Right touch switch portion.
Lower-left locking mechanism can have multiple with the concrete structure of bottom right locking mechanism, as a example by the locking mechanism of lower-left, such as lower-left
It is rotatably connected to latch hook on push rod 12, left front support 11 has lockhole, latch hook and the left touch switch portion being rotationally connected
122 are connected by traction piece, are provided with so that latch hook tends to inserting the small part in lockhole between latch hook and lower-left push rod,
And be provided with so that left touch switch portion 122 pops up and overcomes small part between left touch switch portion 122 and lower-left push rod
Elastic force thus drag the big elastic component that latch hook departs from lockhole.Or can also is that another kind of structure, as latch hook slides even
It is connected on the push rod of lower-left, is provided with between latch hook and lower-left push rod so that latch hook tends to departing from the first elastic component of lockhole, left touch-control
Switch portion 122 in upper and lower strip, left touch switch portion 122 slide be located on the push rod of lower-left and be provided with between the two so that
The second elastic component upspring in left touch switch portion 122, when upper left putter body 221 is pressed in left touch switch portion 122, left tactile
Control switch portion 122 is pressed on latch hook and inserts it in lockhole.
When upper left push rod 13 relative lower-left push rod 12 launches, the bottom of upper left putter body 131 and left touch switch portion
122 is inconsistent, and now, lower-left locking mechanism is in the lock state down, leans on when upper left push rod 13 relative lower-left push rod 12 folds
When holding together, the bottom of upper left putter body 131 is separated with left touch switch portion 122, and now, lower-left locking mechanism is in solution
Under lock status；
When upper right push rod 23 relative bottom right push rod 22 launches, the bottom of upper right putter body 231 and right touch switch portion phase
Conflicting, now, bottom right locking mechanism is in the lock state down, when upper right push rod 23 relative bottom right push rod 22 folds and draws close,
The bottom of upper right putter body 231 is separated with right touch switch portion, and now, bottom right locking mechanism is under released state.
